Please help me to find the answers for the below.

1. Purpose of DNS
2. Purpose of NetBIOS
3. How DNS & NetBIOS will Impact on web site

Thanks

Do your own homework. Here's a start:

DNS -- Domain Name Service. This is the address lookup (phonebook) system for the internet (Web). It relates an IP address with a domain name and propagates that information around the world, so that everyone who wants to look up www.google.com can get an IP route (74.125.93.106) to the right systems that will respond to the packet. You generally need DNS to use most web services. Some larger internal networks use DNS as well to resolve names inside of the LAN. Small home networks like mine use other services to resolve names inside my LAN.

NetBios -- this is part of MS LAN Manager IP protocol stack, it's one of the ways that systems can resolve a network IP to a server name using the CIFS/SMB protocol. You don't need DNS in this case.

I'm not a network guru, but that's my take on it. I'm sure others will add their corrections.

In a nutshell, your website won't and probably shouldn't use netbios (I don't think it routes...but I'm not sure). You would only use it for internal network SMB traffic.

Actually, NETBIOS is not any part of the TCP/IP protocol suite or stack. Microsoft, is using TCP/IP to transport NETBIOS/NETBEUI commands, because NETBIOS/NETBEUI is a non-routable protocol (it has no "network portion" in it's addressing structure ... it's all host - name<->MAC).

Back in the Good Ol Days, when PCs were much weaker, the networking logic was contained on the networking card (partially as a chip, partially loaded by the OS/Driver).
IBM was the first to implement in the general market with their broadband NIC. NETBIOS (later NETBEUI) was the command logic to identify the hosts on the network, and do things like re-direct disk requests (via INT13) to/from the network on hosts identified and configured as "server" resources.

Microsoft (3COM too, to some degree) fought, kicking and screaming, virtually all other networking protocols, including TCP/IP, to get their networking solution (LANMAN / NETBIOS /NETBEUI) to reign supreme ... and came up with NB over TCP only when it was apparent that IP was gonna win that battle.

Thanks guys for your answers. Actually I did a full search on the internet for DNS & NetBIOS. I just wanted get an understanding for the 3rd question.(How DNS & NetBIOS will Impact on web site).

So as per your answers you mean that NetBIOS doen't impact in web sites. It's only used for resolve a network IP to a server name and doesn't involve in internet web sites. (I mean to search a web site like)
Thanks.

turn off netbios for the love of god!

That would be incorrect.

NETBIOS/NETBEUI are parts used with other transport protocol suites, like TCP/IP is a transport protocol suite (or IPX from Novell). It describes how hosts are identified, located, the process for establishing and maintaining a session, and ending a session. Part of that suite of "how to" includes mapping a name/ID to a MAC address. Initially it operated as a complete system, and later evolved to a system operating in conjunction with some other transport.

NETBIOS/NETBEUI is a basically command structure that operates above other transport protocols. It started as a system for integrating non-local resources (disk, printer, messaging) into DOS (which had not concept of "network," only the local host) or sharing resources with others on a common network segment.

Because you seem to be search impaired: http://en.wikipedia.org/wiki/NetBIOS
or www.google.com, search for "NETBIOS and NETBEUI"

Read the links and decide for yourself whether NB has any role in operating a web or other public resource service.

Good Luck

This is a much more correct and concise answer than mine. Props!

 

[benedictme]

Thank you all. I were able to roundup my question with your answers. Thanks again for your help.

Agreed. Killed it network wide here, so much less useless chatter.
